Remove Site Role and Forum Role from admin user listing.

I’ve tried the usual in my functions.php file and from my plugin but the columns aren’t being removed. Perhaps bbPress is loading after that function has run and therefore they’re not being unset?
`function edit_admin_columns($columns = array())
{
unset($columns[‘role’]);
unset($columns[‘bbp_user_role’]);
return $columns;
}
add_filter(‘manage_users_columns’, ‘edit_admin_columns’);
`
